Re: Reversing Ring and Macro photography

Hi Alis,

I don't know if a zoom lens is the best choice for this technique. With a 50 mm lens it works very well. I did this ages ago with my olympus om2 and 50 mm lens. The results were very nice. Bus AFAIR zoomlenses were giving bad results those days ( around 1980).
It can be that the latest zoom designs give good results but I'm not sure about this.

Re: Reversing Ring and Macro photography

Hi Alis,

If I remember correctly, the reasoning behind reversing the lens was, that normal lenses are calculated for when the image is closer to the lens than the subject. In macro larger than 1:1, you find yourself with the subject closer to the lens than the image (film/sensor), so reversing the lens should get you better quality.

In film days, such macro work often involved bellows (which often implied NO aperture transmission anymore...), manual focussing etc., so lots of fussing anyway (been there...), reversing the lens wasn't adding any fuss in practice.

If you do it nowadays with an AF camera, you'll still lose all automation. And the macro effect might just be due to moving the lens away of the camera. Personally, I wouldn't bother with reversing the lens, and invest in (a set of ) extension tubes, that let me keep the automation, including autofocus (as long as there's enough light...).

This might interest you as well. I noted especially his remark about exposing all the couplings when reversing a lens...

Re: Reversing Ring and Macro photography

I'm sure this is no substitute for a real macro lens but considering how inexpensive these rings are compared to everything else to do with photography...
My best results came from using my monopod and leaning in and out to focus. And holding my breathe and taking a million shots to get a few keepers.

Re: Reversing Ring and Macro photography

Hi Soma,
If I understand correct you placed the old lens close to the front element of your kitlens?
I think what Alis wants to do is to mount the lens reversed directly to the body.
BTW Your first one is a very nice picture!

Re: Reversing Ring and Macro photography

Yes, the ring I used has two sets of threads. The ring screws to the front of the lens attached to the camera and the second lens screws to the ring by its face. I wasn't aware there was a way to just attach one lens face first to the body. Now I'm curious because the method I fooled around with is kind of a pain in the neck.

I have experimented with this technique but by simply reversing an old Zuiko 50mm f/1.8 against the body flange of the camera. You need to make sure that the lens is pushed firmly against the flange. The advantage of using an older fast prime is that it obviously lets plenty of light in and you can change the aperture manually. You cannot do this with a modern lens (as stated above). You focus by moving the whole rig and theDoF if wafer thin with the 50mm. You can also reverse a second lens onto the lens already fitted to your camera. It is best with two wider primes. Never done this though. The snaps below were experimental using the Zuiko and natural light;

Thanks, Hansm! Very helpful.

I have a 5mm lens and I might try it like others suggested by holding it in front of the camera for now.

Thanks, Remco! Very interesting article. I used to work in entomology lab on tick-borne diseases back in my earlier days of research and remember my advisor asked me to take pictures of the ticks for a presentation. I wish I knew about this technique back then

Thanks, Steve! Very nice set of pictures. Makes me want go try it right now. It is all new territory for me. From optics to actual mechanics of it.
